Title: Coil winding method
Inventor: KATOU KAZUO
IPC: H01F41/06
Filed: 1982-02-24
Abstract: PURPOSE:To obtain a uniform coil winding by forming a resonant circuit consisting of a wound coil, obtaining a winding error from a resonant frequency and by compensating a coil winding data through numerical control. CONSTITUTION:When an independent coil 13 is formed by winding a wire material to a stick 7, an elastic contact 16 is placed in contact with a contact 17 of stick and a resonant frequency f1 of resonant circuit formed in combination with a detector 12 is thereby output. The frequency f1 is compared with the reference frequency fo of the coil 13 being stored in a memory 14 and a deviation indicated by a digitalized voltage value is sent to a small size operation circuit 11' as a compensating data. The operation circuit 11' selects a winding method to be compensated in a coil to be formed next in accordance with a winding data stored with the winding pitch and controls a number of rotations and amount of movement of nozzle 5 on the numerical control basis, completing the next coil. As explained above, a winding error is fed back to an automatic winding apparatus and therefore a uniform and accurate coil winding can be realized.

Title: Differential amplifier
Inventor: RUDEI YOHAN FUAN DE PURATSUSHI
IPC: H03F3/30
Filed: 1990-02-13
Abstract: PURPOSE: To directly fetch both single ended class-A signals and differential class-A signals from the output terminal of a differential amplifier by connecting the collectors of third and fourth transistors to a second power terminal through a common third resistor and to the base of a fifth transistor the emitter of which is connected to a common terminal and the collector of which is connected to the second power terminal. CONSTITUTION: The collectors of transistors T3 and T4 are connected to a second power terminal VCC through a resistor R5 and, at the same time, through the base-collector junction of a transistor T5. The common terminal 5 composed of a node between the connected collectors of transistors T1 and T2 is connected to the emitter of the transistor T5. Therefore, the sum of currents flowing through the transistors T3 and T4 flows through the resistor R5 and the sum of currents flowing through the transistors T1 and T2 flows through the transistor T5. The potentials at output terminals 3 and 4 are decided by the total voltage drop among the resistor R5, the base-emitter junction of the transistor T5, and a resistor R3 or R4 having nearly the same resistance value.  When the design is appropriate, the potentials are positioned at the center of the total output voltage swing and class-A operations can be obtained.

Then an item generating part 27 generates the items at each parts generation start position when only a PICTURE character string exists. Meanwhile a header generating part 28 generates the headers at each parts generation start position when the character strings other than the PICTURE character string exist.

Abstract: PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine to protect an engine by gradually reducing the misfire rotation speed of an engine during the occurrence of abnormality without using a high capacity capacitor. SOLUTION: When no abnormality occurs to an engine and an abnormality detecting switch 6 is opened, a transistor TR1 is conducted and a voltage into which a control voltage Vq is branched by resistors R1 and R2 forms a reference voltage Vr. When abnormality occurs to an engine and an abnormality switch 6 is closed, the transistor TR1 is disconnected and intermittently charging a capacitor C1 with the control voltage Vq the reference voltage Vr is raised by an amount equivalent to voltages at the two ends of the capacitor C1.  A detecting voltage Vn having a crest value decreased with the increase of a rotation speed is compared with a reference voltage Vr, and when a state that before an ignition command signal Vio is generated, a reference voltage exceeds a speed detecting voltage is produced, the feed of an ignition signal Vi to an ignition circuit 1 is blocked and an engine is brought into a missfire.
